Joe,

The OS is 64-bit. The JVM can either be 32 bit (runs with PASE out of
/QOpenSys) or classic 64 bit (no PASE, in /QIBM). The 32 bit java uses
less memory and loads quicker. Now add in 6.1 into the picture and you
have even more options.

5761JV1 6 Java Developer Kit 1.4 (64 bit classic)
5761JV1 7 Java Developer Kit 5.0 (64 bit classic)
5761JV1 8 J2SE 5.0 32 bit
5761JV1 9 J2SE 5.0 64 bit
5761JV1 10 Java Developer Kit 6 (64 bit classic)
5761JV1 11 Java SE 6 32 bit
5761JV1 12 Java SE 6 64 bit
